ASSEMBLY INSTRUCTIONS
CAUTION
When connecting the water inlet to the water
supply mains, local regulations of your water
company must be observed. In some areas
the unit must not be connected directly to
the public drinking water supply. This is to
ensurethatthereisnofeedback ofchemicals
in to the water supply. Direct connection via
a receiver tank or backflow prevented, for
example, is permitted. Dirt in the feed water
will damage the unit. To avoid this risk, we
recommend fitting a water filter.
■Garden hose must be at least 5/8 inch
diameter.
■ Flow rate of water supply must not fall below
2.5 GPM (gallons per minute)
■Flow rate can be determined by running the
water for one minute into an empty 5-gallon
container.
■ The water supply temperature must not ex-
ceed 104°F/40°C.
■Never use the pressure washer to draw in
water contaminated with solvents, e.g. paint
thinners, gasoline, oil, etc.
■Always prevent debris from being drawn into
the unit by using a clean water source. Use
additional water filter.
